Bitcoin’s going through an update on August 1st, it’ll either be a soft fork or a hard fork. SegWit needs more signals from miners to get fully approved and ready to go, and if it doesn’t and some decide to switch anyways then that’ll cause everything to split. There will be 2 versions of Bitcoin, just like Ethereum came out with Ethereum Classic. Bitcoin Unlimited (Bitcoin ABC) and Bitcoin Core. This will rock the prices.. so definitely check out the links below and stay safe. I’d hold your bitcoins in an offline wallet while everything settles through, and I definitely wouldn’t trade or send/receive around the time of the updates!
